BRONZING AND DUSTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 333,207, dated December 29, 1885.

Application filed September 17, 1885. Serial No. 177,320. (No model.)

To all whom it may concern:

Be it known that we, RUDOLPH F. EMMER ICE and FREDERIoK VONDERLEHR, both of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Bronzing and Dusting Machines, of which the following is a specification.

In ornamenting paper with bronze-powder the design is first printed on the paper with adhesive substance, after which bronze-powder is applied and the paper, is dusted, to remove therefrom the surplus powder. In the bronzing-machine the paper, after the powder is applied, is subjected to a preliminary dusting operation and is afterward passed through a dusting-machine,t0 complete the removal of the bronze-powder.

Our invention may be embodied in machines for bronzlng, or in machines for dusting only, or in machines which may be employed for either purpose; and the object is to provide a compact, durable, and simple machine,which will accurately take the sheets of paper presented to it, and which will perform the desiredwork very rapidly.

The invention consists in novel combinations of parts hereinafter described,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of a machine Fig. 2 is a trans- Fig. 3 Fig. 4

verse vertical section of the machine. is an end elevation of the machine.

\ is a transverse vertical section on the plane of the dotted line w 00, Fig. 1, looking toward the left of said figure; and Fig. 5 is a transverse section, on a larger scale, illustrating the grippers and their operating-mechanism.

Similar letters of reference designate corresponding parts in all the figures.

A A designate the two end frames or standards of the machine, and B is a shaft or round bar, the ends of which-are fitted to and secured against rotation in sockets or hubs a on the end frames A.

O O designate large wheels,which are fitted to turn on the shaft B, and are arranged one at each end of the machine and near the frames A. These wheels have spur-teeth on their peripheries, and are driven in unison by pinions 1) on a main or driving shaft, D, to which motion is given by a belt, 1), running on fast and loose pulleys 12 b These wheels are connected by a bar, 0, which extends between their peripheries and has hinged adjacent to it a second bar or narrow plate, 0. These two parts, 0 0, form the fixed and movable jaws of the gripper, and with the wheels 0 form a rotary carrier for the sheets which are taken from the feed-board E.

The hinged gripper member 0 may be operated by a cam and any suitable connections. As here represented, it is closed by a spring, 0 when not otherwise acted on, and has upon one end a small pinion, 0 with which engages a second pinion, c, which turns loosely on a stud attached to one of the wheels 0. Also fulcrumed at c to one of the wheels 0 is a lever, 0, carrying at the outer end a sector, 0", which engages with the pinion. c, and bear: ing at the inner end upon a cam, a, formed upon or attached to one of the end frames, A.

The gripper-carrier turns in the direction indicated by the arrow in Fig. 2, and before the grippers have completed a revolution they are opened by the cam 0 and the sheet is deposited on the receiving-board E. The gripper a is thereafter held open by the action of the cam until it reaches the feeding-point, and is then closed by the spring 0', and caused to grip the sheet. The grippers and the gripper-operating mechanism are best shown in Figs. 4: and 5, but also in Fig. 1.

In order to enable the sheets to be presented accurately to the grippers, we employ a pivoted or movable gage, d, which is operated through a rod, d, by a cam on one of the wheels 0. This gage is like those ordinarily employed in bronzing-machines, and forms no part of our invention.

Arranged between the wheels 0 and within the rotary path traveled by the grippers is a casing or box, F, which is of circular or cy- 1 lindric form, with a portion removed beneath the feed-board E. This box or casing' F is nonrotary, and is supported by the shaft or bar B. Within it is arranged a rotary brush, G, which worksin an opening, 6, in the periphery of the box or casing, and opposite this brush and beyond or outside the circular path traveled by the grippers is a second brush, G, journaled in a box or casing, G. The sheet of paper carried by the grippers passes between the brushes G G, which clean its opposite sides, and is then deposited on the board or table E. These brushes may be like those ordinarily used in bronzing and dusting machines, and are here shown as having parallel rods 0, over which are folded flaps or pieces of cloth, the edges of which are presented outward and form the dusting-surface. The outer brush, G, is driven by a belt, 0, from a a pulley, 6 on the main shaft D, as best shown in Fig. 3, and'the inner brush, G, is driven by a belt, e, from a pulley, e, on a shaft, 6 which extends lengthwise through the box F, and has its bearings in the ends thereof. shaft 9 receives rotary motion by a pinion, e, from a wheel, 6 which is fast upon and turns with one of the wheels 0, as shown in Fig. 4.

At the top of the machine-we have represented a fountain or box, H, for bronze-powder, which is furnished with the usual plush or other roller, 7, for distributing the powder upon the paper carried beneath it. This roller fmay be driven by a-separate belt, and when the fountain H is in place the machine may be used for bronzing and for performing the preliminary dusting operation. When the fountain is removed, the machine may be used for dusting alone.

It will be seen that the machine is very simple in construction and has few parts.

Machines for dusting paper have been made in which the grippers are carried by endless chains having a considerable length of horizontal travel. Such machines are cumbrous and occupy considerable room, and are also objectionable because the wear of the chainlinks and pivots soon makes the chains slack, and if provision be afforded for taking up the slack the chains will then be elongated and the grippers will not work as accurately.

In our improved machine the length of travel of the grippers must always remain uniform, and the grippers will always be operated accurately and in proper time. As the grippers travel in a circle, the machine may be worked very rapidly, and it is very compact and oocupies but little floor-space.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, with a feed-board and a rotary carrier provided with grippers for grasping sheets, of rotary brushes arranged within and without the circular path trave'rsed by the grippers, and boxes containing the brushes and receiving the powder and dust removed by them, substantially as herein described.

2. The combination, with a feed-board and a rotary carrier provided with grippers for grasping sheets, of a box or casing of circular form arranged within the gripper-carrier, a rotary brush journaled in said box or casing and working through an opening therein, to brush the innersurface of the sheet, anda rotary brush arranged outside the path of the grippers, to brush the outer surface of the sheet, substantially as herein described.

3. The combination, with a feed-board and a rotary gripper-carrier provided with grippers, 01' a spring for closing the grippers, and a cam, a lever, and gearing for opening them, brushes arranged within and without the circular path of the grippers, for brushing opposite sides of the sheet, and boxes containing the brushes and receiving the powder and dust removed by them, substantially as herein described.

4. The combination, with the feed-board and a rotary gripper-carrier provided with grippers, of a box or casing, F, arranged within the path of the grippers, a brush journaled in said box or casing, for brushing the inner surface of the sheet, a brush arranged outside the path of the grippers, for brushing the outer surface of the sheet, a main shaft and gearing for driving the rotary gripper-earrier, a counter-shaft journaled in the said box or casing F, and gearing through which it is rotated from the carrier, and belts and pulleys for driving the two brushes from the main and counter shaft, substantially as herein described.

5. The combination,with the two end frames, A, and the non-rotarybar B, connecting them, of the gripper-carrying wheels 0 O, journaled on said bar, the box or casing F, supported on said bar between said wheels 0 O, and the brushes G G, arranged within and without the path of the grippers, for brushing opposite sides of the sheet, substantially as herein described.
